The ductile-brittle transition is exhibited in bcc metals, such as low carbon steel, which become brittle at low temperature or at very high strain rates. Fcc metals, however, generally remain ductile at low temperatures. In metals, plastic deformation at room temperature occurs by dislocation motion.

After surgery to repair a Grade III strain, most people regain normal muscle function after several months of rehabilitation. External resources
